暗光下阅读伤眼是迷信吗?为啥看电影就没事?【认真日常】【AI总结】【英语阅读溯源】


简单地说,就是电影院里的光远不如电视的光亮——因为电影幕布是反光,电视是发光。
(扇贝的这个选段里头把电影院的部分删除了……在评论区看到有同学吐槽看了半天没看到想看的)

短评:这里其实列出亮度计测量的数值更合适,反光的强度未必就不如发光;很遗憾原文没有引用相关调查。
知乎简单搜索了一下,没找到讲原理的回答。
找到一个Quora上“看电影跟黑屋子看电脑一样伤眼嘛?”问题下,名为Adrian Mudd的朋友的回答,大意是看电影的时候因为屏幕比较大所以我们会无意识地转动眼球;真实性存疑,因为没有放参考文献😂

同一个问题Leo Enticknap的回答也是在讲反射光与直射光比起来更不容易让人疲劳;得到了另一个人的赞同……不过同样没有参考文献


ChatGPT对原文的总结:
目前没有科学证据表明在黑暗或光线不足的环境中阅读会对眼睛造成永久性损害。然而,这可能会导致眼睛劳损,出现瘙痒、流泪、发红等讨厌的症状,可以通过避免来减轻。在暗光环境中阅读需要眼睛更努力地适应,瞳孔会扩大以让更多光线进入,眼睛内的肌肉也会因为长时间用力而感到疲劳。为了避免眼睛劳损,应该确保阅读环境光线适中,经常休息、多眨眼,避免长时间过近距离阅读屏幕或书籍。此外,花更多时间在自然光线下也有助于保护眼睛免受近视等问题的影响。尽管在黑暗中阅读并不像传统上认为的那样糟糕,但好的视力是我们不应该忽视的。在我们还能做到的时候,应该尽量避免任何眼部问题。
额外内容:
这次,我简单瞅了一眼参考文献的摘要并且每个参考文献留了一句话概括,感兴趣的朋友可以继续往下看。

这篇科普文同样给出了参考文献,

What Happens To The Eyes In Dim Light?
[Research](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7487012/) says that our eyes work harder than usual in low-light situations. While reading in dim light, your pupils have to dilate more to let in as much light as possible. The light-sensitive cells in the back of the eyes have to work harder than they would in normal daylight.


This extra work is necessary to compensate for the lack of sufficient lighting. This helps your brain process the information of what you manage to see while straining. When we stare at a screen or a book for hours in dim light, the muscles inside and around our eyes quickly become strained.
So, is it okay to look at a screen when the room is dark? The digital screen is where the light is coming from, after all.
Not really. [Studies](https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwiD29b49Nz9AhX0ILcAHQLfCY44ChAWegQICBAB&url=https%3A%2F%2Facademicjournals.org%2Fjournal%2FMPR%2Farticle-full-text-pdf%2F0905F9948599&usg=AOvVaw2Ad3AdvvMQkIToBUbzvQHk) 【这个链接无法访问(doge)】reveal that staring at anything (not just a screen) for too long can make your eyes tired, as you are concentrating too much on it, so you tend to [blink less](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2776336/). Staring at a screen in a dark or dimly lit room causes even _more_ strain, especially if you are too close to the screen or book for prolonged periods of time.

Also, when a screen is much darker (or brighter) than the surroundings, our eyes must work harder to see it.
Regardless of the lighting situation, when we focus on a smartphone for too long, it may actually make our eyeballs become longer, from front to back. This becomes especially evident in the vitreous chamber (the large space in the eyeball filled with jelly-like substance). Once the eyeball elongates too much, as we keep focusing on near objects, [it can lead](https://doi.org/10.1016/S2589-7500(21)00135-7) to myopia or short-sightedness (a condition in which near objects would appear clearly, but distant objects seem blurred).
